MANIFOLD-MOLD.

Specification of Letters Patent.

Application filed May 11, 1910.

Patented Feb. 14, 1911.

Serial No. 560,580.

To all whom it may concern:

Be it known that l, ConNnmns Gonnan, a citizen of the United States,residing in the city and county of Philadelphia, State of Pennsylvania,have invented a new and useful lVIanifold-Mold, of which the followingis a specification.

My invention relates to molding devices and consists of a novelconstruction of a manifold mold by the employment of which I am enabledto entirely dispense with the use of anchors.

It further consists of a novel construction of a manifold mold inconjunction with which a sand core is employed and wherein a casing maybe produced which is harder on the exterior portion than on the interiorportion thereof.

It further consists of a novel construction of a manifold mold whereinprovision is made for the escape of the fumes and gases.

It further consists of a novel construction of the cope and drag whichare connected together in such a manner that a minimum amount of time isnecessary to open the mold.

It further consists of a novel construction of manifold mold wherein aplurality of latorally extending apertures con'nnunicating with theatmosphere are provided.

It further consists of other novel features of construction, all as willbe hereinafter fully set forth.

For the purpose of illustrating my invention, I have shown in theaccompanying drawings one form thereof which is at present preferred byme, since the same has been found in practice to give'satisfactory andreliable results, although it is to be understood that the variousinstrumentalities of which my invention consists can be variouslyarranged and organized and that my invention is not limited to theprecise arrangement and organisation of these instrumentalities asherein shown and described.

Figure 1 represents a perspective view of a manifold mold, embodying myinvention. Fig. 2 represents a longitudinal sectional View thereof, butshowing in addition the sand core and casting. Fig. 3 represents a sideelevation of a portion of a finished casting. Fig. 4 represents asection on line 00-m- Fig. 2.

Similar numerals of reference indicate corresponding parts in thefigures.

Referring to the drawings :-1 designates a manifold mold or flaskembodying my invention, the same consisting of the cope 2 and the drag 3which are movably connected together in the present instance by means ofhinges 41, it being apparent from Fig. 1 that. dowel pins 5 are securedto the drag which cooperate with apertures (3 in the cope 2. Both thecope and the drag are preferably provided with suitable handles 7. Thegate 8 in the present instance, as well as the risers 9 are formedpartly in the cope and partly in the drag.

10 and 11 designate apertures formed partly in the cope 2 and partly inthe drag 3 and through which the ends 18 of the sand core 14: areadapted to extend, such ends forming a shoulder 12. The body of the copeand drag is recessed in any desired manner and in the present instancethey are provided with the semicircular recess 15 having at its ends inproxin'iity to the apertures 10 and 11. the flange forming recess 16.The sides of the mold opposite to the gate 10 are provided with adesired number of boss forming recesses 17 communicating with theapertures 18 which extend completely through the sides of the mold.thcrebv adapting the same to receive the lateral extensions 19 of thesand core 14:.

2O designates the casting which is obtained by the employment of theconstruction shown in the drawings for thepurpose of illustrating oneform of my invention.

It will be apparent to those skilled in this art that by the employmentof my novel construction of manifold mold I am enabled to dispenseentirely with the use of anchors. Tt: will be further apparent thatowing to the provision of the novel construction and location of theapertures 18. that the gases and fumes may readily pass from theinterior of the mold to the atmosphere. whereby I am enabled to producea much better casting than if all of the fumes and gases are re tainedwithin the mold.

It will now be apparent that I have devised a novel and usefulconstruction of a manifold mold which embodies the features of advantageenumerated as desirable in the statement: of the invention and the abovedescription. and while T have. in the present instance. shown anddescribed a preferred embodiment thereof which has been found inpractice to give satisfactory and reliable results, it is to beunderstood that the same is susceptible of modification in variousparticulars Without departing from the spirit or scope of the inventionor sacrificing any of its advantages.

Having thus described my invention, What I claim as neW and desire tosecure by Let ters Patent, is

1. A manifold mold consisting of a cope 2, a drag 3 having commonthereto, a core receiving chamber communicating With a row of laterallyextending core receiving apertures 18, the latter extending through oneside only of said mold, the latter also having core receiving apertures10 and 11 in the ends thereof, a gate 8 for said mold, and risers 9,said risers 9 being located in the side opposite to said side apertures18, all of said apertures 18, 10, 11 and 9 being open to the atmosphere.

2. A manifold mold consisting of a cope 2, a drag 8 common thereto,whereby a core receiving chamber is provided, said core receivingchamber communicating with a row of laterally extending core receivingapertures 18, the latter extending through one side only of said mold,the latter also having core receiving apertures 10 and 11 in the endsthereof, a gate 8 for said mold, and risers 9, said risers 9 beinglocated in the side opposite to said side apertures 18, all of saidapertures 18, 10, 11 and 9 being open to the atmosphere, in combinationwith handles.
